WATCHCASE.

Application led August 14, 1922. Serial No. 581,802.

To all whom t may cof/teem.'

Be it known that I, Josemi LAsiio, a citizen of the United States,residing at 309 Grand Street, borough of Manhattan, city of New York,have invented a new and useful Improvement in Watchcases, of which thefollowing is a specification.

This invention relates to improvements in watch cases and moreparticularly to that class known to the trade as two-piece cases such asare commonly used on wrist watches.

One of the objects of the invention is to provide a case wherein it ispossible to examine the inner surface of the back cover of the case andthe watch movement without the necessity of removing the movement fromits position in the case.

Heretofore in the assembling of such watches, it has been customary tosupport the movement in the back cover of the case in Such a manner thatwhen the case was opened, the dial face and the inner surface of thefront cover only were visible, thus necessitating the removal of themovement from the case if it was desired to expose the movement andindices on the case.

Another object of the invention is to provide for snugly encasing themovement within the front cover of the case and to exclude dust andother foreign particles from entering into the spaces ordinarily eX-isting between the circumference of the movement and the encompassingcover. This object is achieved by providing a loose ring, shapedexternally to fit snugly within the watch case and shaped internally tofit snugly around the movement. f

As a further object the invention contemplates the provision of a novelmeans for holding the case closed, which also acts to hold the ribbon orwrist band connected to the case.

With these and other objects in View which will become more apparent asthe description proceeds, 'the invention consists in the novelconstruction, combination and arrangement of parts which will be fullyset forth in the following specification, and illustrated in theaccompanying drawing, in which,

Figure 1 is a face View of this improved watch case, showing the dialface, the movement being in place,

Figure 2 is a rear view of Figure 1 showing the case open, anddisclosing the movement,

Figure 3 is aface View of the ring adapter, Figure 4 is an edge viewpartly in section of Figure 3, and

Figure 5 is an enlarged fragmentary sectional view of the caseillustrating in detail the means for holding the same closed.

Referring to the drawings in detail, the numeral 10 designates in itsentirety the watch case which comprises the front and back covers 11 and12 respectively, hinged together as at 13. The front cover 11, isprovided adjacent the hinge 13 with a loop 14 through which the wristband or ribbon (not shown) is passed, and secured to the front cover. Atthe opposite side is a similar loop 15, the ends of whichvare passedthrough openings 16 in the cover and turned outwardly as at 17 'toengage in indentations 19 formed adjacent the matching edge of the backcover 12.

Fitted into the front cover 11 is a ring adapter 20 shaped externally tofit the inner contour of the cover 11 and this ring is shaped internallyto conform to and receive the watch movement 21. Formed near the outeredge of the ring 20 is an internal annular lanige 22 which acts inconjunction with the customary half head screws 23, to retain themovement 21 in place in the ring.

In use, it will be seen that the ring 20 is secured around the watchmovement 21 and then the ring and movement are set into the front cover11 of the case as a unit. Obviously, the ring will act to exclude dustand foreign substances from entering the movement and owing to its snugfit in the cover 11 will cause the movement to remain in said cover whenthe case is opened.

While in the foregoing there has been shown and described the preferredembodiment of this invention it is to be understood that certain minorchanges in the details of construction, combination and arrangement ofparts may be resorted to without departing from the spirit and scope ofthe invention as claimed.

What is claimed is:

1. A watch case comprising a front cover, a back cover hinged thereto, aring adapter removably secured in the front cover to support a watchmovement, means to secure the movement in said adapter, ribbon attachingmeans at the sides of the front cover, and means associated with oneoisaid attaching means for holding the Covers normally in closedrelation.

2. A Watch case comprising a front cover, a back @over hinged thereto,ribbon securing means at opposite sides of 'the front @oven-and arms onone of the ribbon securing means for holding the front and back coversclosed.

3. A combination Watch case, comprising two shells, a hinged jointbet-Ween said two shells, a removable ring fitting into one of saidshells and releasable means adapted to keep said shells in a closedposition, said means comprising two elastic wire pins axially set at theinside of the Wall of one of said shells and two (5o-operating recessesin the Wall of the other` shell.

4. In a Watch case, a shell adapted to receive the movement of theWatch, a second shell to be used as a. Cover for the first shell, Wirecatches axially and yieldingly set at the inside of the Wall of one ofsaid shells and impressions provided inthe Wall of the other shell andadapted to receive said wire catches and keep said two shells in aclosed position thereby.
